Introduce the principles of toxicology with a lab activity. By exposing blackworms to a toxicant in varying concentrations, participants collect and analyze data, and witness and discuss concepts - including exposure pathways, nature of effects, acute and chronic exposure, dose-response, and reversible and irreversible effects.
